I have a 92 Camaro and just the other day i think the tranny went out but im not sure. 1st and 2nd work fine but when it is in overdrive it wont shift into overdrive. I dont know much about the 700-R4 but i was wondering if it is something small. The tranny does have 190,000 miles on it i believe but it leads me to think that its not the tranny that went out but some electrical or mechanical problem. I noticed the overdrive slipping before but let it go. If anyone has any idea of what happened, let me know. Could it be something simple???

when yur in overdrive and u give it gas to cruise like 40-70 mph does it bog and dont give u acceleration? thats what mine does sometimes, i leave mine in drive

 

The seals for the overdrive servo are not holding fluid pressure as they used to, thereby the 2-4 band material will start to glaze losing its holding ability (no 4th) & possible low pressure due to the many miles you have, etc. As things wear the leaks/crossleaks in the transmission get more pronounced, as this can be expected with as many miles as you have. The 1992 & early 1993's 700R4's came with the most fixes (updates) from the factory. I have seen many of these with well over 150K miles still in fair shape as compared with earlier 700R4's. Second gear (uses the same 2-4 band) might still hold for a little while. When this problem occured did the shift points at light throttle change? If it did (& the shifts got earlier) then the TV cable lost its adjustment. But with as many miles as you have, this can/might be expected.
Hope This Helps!!!

 

Yes it did. Earlier it was slipping. You could tell the shifts points were changed. I assume the transmission is shot. DO you know were I could get one rebulit for cheap.
